Table 1. Pin Description
Description
TTL compatible horizontal sync input (separate or composite)
TTL compatible vertical sync input (for separated H&V)
First PLL lock/unlock output (0V unlocked - 5V locked)
Second PLL loop filter
Horizontal oscillator capacitor
Horizontal oscillator resistor
First PLL loop filter
Horizontal position filter (capacitor to be connected to HGND)
Horizontal moire output (to be connected to PLL2 C through a resistor divider)
Vertical dynamic focus output
Horizontal section ground
Horizontal Flyback input (positive polarity)
Horizontal section reference voltage (to be filtered)
B+ error amplifier output for frequency compensation and gain setting
Regulation input of B+ control loop
Sensing of external B+ switching transistor current
Ground (related to B+ reference adjustment)
DC breathing input control (compensation of vertical amplitude against EHV
variation)
Vertical section ground
